Accepting a new job offer
When accepting a job offer be enthusiastic and back up your verbal confirmation with a letter of acceptance.
It's really important to let the employer know that you are looking forward to working with them and will ensure you get off to a good start in the role. You should back up your verbal confirmation with a letter of acceptance, and expect a letter of appointment in return. Make sure you get formal confirmation of your new position, including start date and time and any forms you may need to supply or complete.
What if I don't hear anything after my offer?
Your new employer will want to ensure you start as soon as possible but it still might take a few days to get the offer letter to you. Try not to call every day for an update but make a note of when the letter should reasonably be with you and then call to follow up.
Take yourself off any jobsites you might be registered with
As soon as you accept a new job, you're morally obliged to take yourself off all job sites and notify any recruitment consultancies who may have been acting on your behalf. If you are on any other shortlists or have any outstanding applications, inform the companies concerned.
It goes without saying that you also need to let your current employer know you're resigning. Check the terms of your contract with them and make sure you give them adequate notice.
