Voicemail:

The company hasn’t been doing well. We’ve had to let some people go, and you’ve been affected. As of today, you’re off the payroll.

Letter:

And the prize goes to… text message:

Hi Katy its alex from the shop. Sorry 2 do this by text but ive been trying to call u + ur phones been switched off. Ive had a meeting with jon + ian and weve reviewed your sales figures and they’re not really up to the level we need. As a result we will not require your services any more. You will receive your last pay packet on Friday 28th july. Thank you for your time with us. (You’ve got mail: ‘We’re letting you go’)
