I left a company (let's call them company A) in February that I had been with for many years.
Started a new job, hated it and quit within the week. Struggled to find work since then. Been unemployed.
Company A then phoned me last week asking if I wanted to rejoin them as multiple projects had started and they were understaffed. I played it cool but knew I was going to say yes. Also acted like I was really enjoying my new role. This helped leverage a higher salary as they were worried I wouldn't rejoin them.
I go back next week. No references or anything as they've known me for years.
Question is, will they be able to find out I lied about being in employment since I left them? Can they check my employment history? Or find out via my tax codes, or work it out by calculating my NI etc etc?
It wouldn't be the end of the world as they're super chill but it would be rather embarrassing.
