There are multiple resources for jobs in Essex, and most can be found online by searching ‘jobs east essex’.
Chelmsford JobCentre Plus is a good first port of call
It is worth also touring local shops like the Co-op, One Stop and Tescos – they often post jobs available on their information boards.
Another good tip is to join Facebook and then join the Burnham-On-Crouch JUICY GOSSIP group – which often posts jobs available. In May 2018 ‘Juicy Gossip’ had 12,000 members – and it continues to grow.
