A key challenge presented by the COVID-19 pandemic was the need for people to be versatile about the type of employment they undertake. Suddenly whole sectors of the economy were closed down and opportunities for employees to switch into another area of work were limited by the almost inevitable requirement for previous experience. Employers are notorious for preferring prospective employees who already have experience of a particular work role and for not wishing to spend money on education or training.
In the context of COVID-19 this meant that people remained unemployed unnecessarily. In the wider context of pre- and post-COVID times it means that employees often become trapped within a certain sphere of work. This is not a good situation for either the employee or the employer. The employee is not fulfilling their potential, and the employer has a workforce which is bored and apathetic.
