Key off, train off then **** off. Don’t think about it until next shift.
The only stress is making sure you turn up in time. You make your own stress in this job so it’s important to relax and not overwhelmed by everything. Once you get a bit of experience everything should fall into place automatically.
As for emails, well it was a few months ago that I discovered that I actually had an email account with my company! Only been working there 17 years! Had hundreds of unread emails but clearly it’s not impacted my job one iota so I’ll log in once or twice a year to keep my password active.
