US corporate training expenses significantly increased in 2017, rising 32.5% to $90.6 billion. Expenses like travel, facilities, equipment, and accommodation costs rose from $26.1 billion to $44.5 billion. Additionally, employee disengagement in training and development is estimated to cost US companies $500 billion annually in losses. Poor training also leads to high employee turnover, with 40% of employees leaving their company within the first year. The e-learning market is projected to exceed $200 billion by 2024 as more companies adopt bring-your-own-device policies to allow training access on employee devices without time restrictions.
