The following days are a jumble of gunfire, digging, gobbled food, soldiers running in and out of the forest in small groups, distant explosions, stray shells, bandaged heads and unexpected lulls. On the very first day, before dawn, I am ordered into one of the newly dug trenches. I huddle there, squeezing my magic buttons and singing songs to the dog. When the fighting stops, the dog disappears, but a new companion takes his place. A strange little soldier crawls along the trench toward me. ‘Private Sasha!’ he cries. ‘I’ve been looking for you all day long!’ He’s old, like a grandfather, a dedushka. He has a black patch over one eye, a tape measure around his neck and a row of pins threaded into his sleeve. Hanging from his belt is the most enormous pair of scissors I have ever seen and I wonder if he uses them as a weapon. He doesn’t tell me his name, so in my head he becomes Dedushka. Dedushka squats, cups his hand to his ear, peers over the top of the trench and smiles. ‘It’s safe to be upright . . . for now.’ He helps me to my feet, dusts me off and commands me to stand as tall and straight as I can. Then he measures me. Everything from head to toe – even my toes! He writes numbers in a little notebook, strings his tape measure back around his neck, salutes and hurries away. It’s all very strange, and I wonder if Dedushka has been bumped on the head during the battle and is now a little bit muddled. I should have given him a hug before he left. I chase after him but stop when I’m hit by a shovelful of flying dirt. Sleepy Bear is digging a cave! ‘Are you going to hibernate?’ I ask. Sleepy Bear chuckles. ‘No, although that would be wonderful! I could do with a lo-o-o-ong sleep.’ He sighs and closes his eyes. He doesn’t open them again and I realise that he has gone to sleep. Standing up! I shake his arm, and he opens his eyes and keeps talking. ‘No, I’m not hibernating. I’m digging a little nook where I can sleep and eat. I’ll hang up my raincape as a door that can open and close so it feels just like a real home . . . except for the lice . . . and the bad smells . . . and the bombs that make the walls shake and crumble.’ He points further along the trench to where other soldiers are digging. ‘We’re all making little houses in the ground.’ ‘Like rabbits and moles,’ I say. Sleepy Bear chuckles. ‘Yes! And soldiers who need to hide from German bullets and bombs.’ He stops digging to roll a cigarette. ‘Should I be making a house?’ I ask. ‘I want to hide from German bullets and bombs, too.’ Sleepy Bear flops to the ground, lights his cigarette, closes his eyes and takes a deep puff. I wait for him to answer, but, instead, he begins to snore! I poke him in the side. He snorts and he murmurs, ‘I think someone has already built you a house, Sasha. Keep going along this beautiful village street and you are sure to find it.’ He falls asleep once more. I kiss his dusty cheek and whisper, ‘Thank you, Sleepy Bear.’ A little way along, I see Cook in a cloud of smoke. He has lit a fire, right here in the middle of the trench, and is stirring a cauldron full of kasha. He squats as he stirs. ‘What are you doing?’ I ask. ‘Cooking supper, of course!’ he cries. ‘But why are you doing it here?’ Cook points his spoon at the ground above the trenches. ‘Because if I do it up there, my pot will be filled with holes from German bullets and all of the kasha will leak out onto the ground. It’s bad enough that our supplies can’t get through German lines and there’s nothing to cook but buckwheat for kasha. But if we lost the kasha, too . . .’ ‘Hungry soldiers,’ I say. Cook nods. ‘And grumpy!’ ‘Like Boris!’ I gasp. ‘Even worse,’ warns Cook. I picture the kasha pot full of bullet holes. And then I realise that if the kasha pot were full of holes, then Cook would be, too. I wrap my arms around Cook’s neck and say, ‘I think this is a very good place for cooking our supper.’ I kiss his smoky cheek and run along. At the end of the trench, I find the biggest hole of all. It’s wide and deep and as busy as a beehive in a blossom tree. Above, a group of soldiers is rolling logs into place for a roof, while below, typewriters rattle and pencils scratch and papers flutter and voices crackle out of five different radios. Their words tangle together to tell a strange wartime fairy tale about German guns and a loving father called Stalin and a Red Army regiment that is lost in the deep, dark forest and a wicked beast called Hitler and a delivery of vegetables that was hit by a bomb and blown into a million tiny pieces too small even to make soup. In the middle of it all, wrestling with a rumpled map, his rifle still slung over his shoulder, is Major Scruff. ‘Major Scruff!’ I run and jump into his arms. ‘Is this our new home?’ ‘Yes, Sasha. I suppose it is.’ ‘Is it safe from German bullets and bombs?’ I ask. He stares at me. ‘Were you scared in the trenches today, Sasha?’ ‘No,’ I reply. ‘I had magic buttons and a dog and some songs to sing. Were you scared in the forest, Major Scruff?’ ‘Yes,’ he says. ‘Poor Major Scruff!’ I press my hand against his cheek. The dark, rough stubble is grubby with grit and his eyelids are taking a long time to open after every blink. ‘You need a shave and a nap!’ I scold. He chuckles. ‘I am too tired to shave and too busy to nap.’ I scrunch my nose while I consider his problem. ‘I know!’ I cry. ‘You nap and I will shave your whiskers. That will be two jobs tumbled into one!’ And so that’s what we do. Major Scruff slumps into a chair and snoozes while I lather his face with soapy water and shave his whiskers. The soap suds travel from his face, up into his hair and down the front of his uniform, and I have to shave his jaw and chin three times because I keep missing bits, but I finally get it all done. I am just wiping his cheeks dry when the dog appears. He licks my hand, then stretches up and licks soap suds from Major Scruff’s ear. Major Scruff wakes with a start. He feels his newly shaved face and cries, ‘Wonderful, Sasha! I feel smooth, clean, rested and ready for action.’ He ruffles my hair. ‘We must do this again tomorrow. Although next time, you might wake me with a gentle shake of the shoulder instead of licking my ear.’

Content guide: Include the presentation title, group members’ names, course/module name, and date. Speaker guide: Briefly say that the presentation explains what employees and companies should consider before sending someone on secondment to Thailand. Slide 2: Agenda / Overview Welcome everyone. Our presentation is about secondments in Thailand. We will cover the main areas that a company and employee should prepare for before relocation. These include finance and housing, work culture, legal and visa requirements, healthcare and safety, and daily logistics such as transport and climate. By the end of the presentation, we hope to show that a successful secondment depends not only on the job itself, but also on good planning before and after arrival in Thailand. Slide 3: What Is a Secondment? A secondment is a temporary work assignment where an employee is transferred to another country, branch, client site, or partner organization while usually remaining connected to the original employer. Secondments require coordination between the employee, home employer, host organization, and local authorities. Slide 4: Finance & Housing — Cost of Living Finance and housing are one of the first things a secondee should plan before moving to Thailand. The cost of living can vary a lot depending on whether the employee is based in Bangkok, another major city, or a regional area. Urban areas usually have higher rent, but they also offer better access to transport, hospitals, offices, and international services. In smaller cities or rural areas, rent may be lower, but transport and convenience can become bigger concerns. So, the key point is that secondees should not only compare prices, but also consider location, commute, and what support the employer provides. Slide 6: Work Culture — Hierarchy & Etiquette Purpose: Help secondees understand workplace expectations. Content guide: Cover respect for seniority, polite communication, indirect feedback, saving face, punctuality, proper greetings, and professional dress. Speaker guide: Explain that foreign employees should avoid being too blunt in meetings and should observe how local colleagues communicate with managers or senior staff. Suggested visual: “Do and Don’t” etiquette list. Slide 7: Work Culture — Industry Growth & Networking Purpose: Connect secondments to career and business opportunities. Content guide: Mention sectors where Thailand often attracts foreign professionals, such as manufacturing, tourism, logistics, finance, technology, and regional business operations. Discuss relationship-building and networking. Speaker guide: Emphasize that trust and long-term relationships are important in Thai professional settings. Networking can happen through industry events, chambers of commerce, company introductions, and informal business meals. Suggested visual: Thailand industry opportunity map or sector icons. Slide 8: Legal & Immigration — Visa Pathways Purpose: Explain the main legal entry pathway for work-related secondments. Content guide: Introduce the Non-Immigrant B visa as a common work/business visa category. Mention that supporting documents may include passport, application forms, employment or company letters, and other evidence requested by Thai authorities. Speaker guide: Make clear that a visa alone may not be enough to legally work; seconded employees normally need the correct visa and work authorization. The exact process depends on the employer, role, nationality, and assignment structure. Suggested visual: Simple flowchart: Home employer → Host company → Visa application → Arrival → Work permit/compliance. Slide 9: Legal & Immigration — Compliance Rules Purpose: Explain ongoing responsibilities after arrival. Content guide: Cover visa extensions, work permit validity, re-entry permits, address reporting, and 90-day reporting for eligible long-stay foreigners. Speaker guide: Stress that compliance is not a one-time task. Employees and HR teams should track deadlines carefully because missing reporting or renewal dates can cause fines, delays, or legal issues. Suggested visual: Compliance checklist or timeline. Slide 10: Healthcare & Public Safety Purpose: Explain how secondees should prepare for health and safety risks. Content guide: Cover international health insurance, access to private hospitals, emergency numbers, vaccinations or health checks if required, and common local hazards such as road safety, flooding, heat, food hygiene, and mosquito-borne illnesses. Speaker guide: Explain that Thailand has strong healthcare options in major cities, but employees should confirm insurance coverage before arrival. They should also know what to do in an emergency and save important contact numbers. Suggested visual: Emergency preparation checklist. Slide 11: Logistics & Climate Purpose: Explain practical relocation and daily-life planning. Content guide: Cover public transit, taxis, ride-hailing, domestic travel, airport access, SIM cards, banking, weather, rainy season, heat, and packing needs. Speaker guide: Mention that weather affects commuting, clothing, housing choice, and travel planning. Employees should plan around heat, rain, and possible flooding, especially during the rainy season. Suggested visual: Seasonal calendar showing hot, rainy, and cool periods. Slide 12: Project Manager / Group Synthesis Purpose: Bring the presentation together and end with key recommendations. Content guide: Summarize the main risks and preparation steps: budget early, secure compliant visa/work permit arrangements, understand workplace culture, arrange insurance, and prepare for climate/logistics. Speaker guide: Conclude by saying that a successful secondment in Thailand depends on both professional readiness and personal relocation planning. End with 3–5 recommendations for companies and employees. Suggested visual: Final checklist: “Before departure,” “Upon arrival,” and “During secondment.” A simple way to divide the work is: Member 1: Slides 1–3 introduction. Member 2: Slides 4–5 finance and housing. Member 3: Slides 6–7 work culture. Member 4: Slides 8–9 legal and immigration. Member 5: Slides 10–12 healthcare, logistics, and conclusion.
